Are there any adapters available to run a standard shock on my 96 beast,or anyone have any suggestions as to how to fabricate one?

Several people have made adapter blocks to mount air shocks. I made one to fit a Manitou swinger to my Oz, and welded an adapter to my strut.

There is concern that the welded adapter does not prevent side to side play, but I really don't notice any because the shock works so well. I may box in the sides some day, but am not in a hurry.

The upper photo of my oz works by extending a shorter shock. I have seen where it can be bolted onto a strut with a thru bolt.

Hope this helps,
Terry

I went with a Risse Astro 5 on my Animal. Figured by the time I bought a shock and fabricated the mount I may as well do the Risse. My Noleen shock is still good but in the cupboard for a spare, I didn't want to risk downtime over the summer if the Noleen decided it had had enough.
I'm impressed with the Astro 5, definitely a step up from the NR4. In fact, I would argue that my Animal set up as it is now is as good as any 08 bike that I almost replaced it with - shudder - how could I even think of doing that.
Just had a 60km gravel road ride tonight - fantastico!

Maybe he has a "Y" Frame Beast?

that'd be more of a challenge!

maybe an Astro-5?

Old photo for reference. I was looking for more rake, and got it, but changed out the fork entirely.

Here is another view of the rear shock.

That looks good,how long has it been modded and how does it ride?

It's been modded about two years now, and is an amazing improvement over the noleen Nr4. I chose a 7.5 inch i2i swinger that tucks right into the cone of the strut. I suppose the side to side flex makes the end of the shock slide against the cone, but except for occasional creaking, mimics the original shock length.

Wow, Terry, that's one crazy angle on your 957's front end. I have Crosslinks on my 4000 and the angle isn't that severe...one thing I noticed is that the links on mine (the top & bottom links to the fork arms) are not parallel...the top is at a steeper angle...if you added a spacer or two under the top link connector to the steerer you'd likely add a bit more rake to your fork, if that's something you'd want).

Just my $0.02...or GBP 0.000000000010

Hmmmm....I don't think you could add any more spacers underneath the Upper Link Mount...........The distance between the crown race seat and the bottom of the ULM is known as the "critical measurment" and there is no flexibility allowed in this measurment according to PRO~FLEX/K2.
It should be 153mm on a standard length OEM Crosslink, and 190mm on "longs"  different measurments if you have a After Market "Taller" ULM.

Fundamentally the maximum distance that this "Critical Measurment" could be is limited by the full extension of the shock, so if you did fit a longer front shock, then that could allow the ULM to move up and thus change the fork rake..
